As of Consul 0.9.1 the cloud provider specific discovery of nodes has been
|
||||
moved to the https://github.com/hashicorp/go-discover library which provides
|
||||
a unified query interface for different providers. To use retry join for a
|
||||
supported cloud provider provide a `-retry-join 'provider=xxx key=val key=val
|
||||
...'` parameter with the provider specific values as described below. This
|
||||
can be combined with static IP addresses and names or even multiple
|
||||
`go-discover` configurations for different providers. This deprecates and
|
||||
replaces the `-retry-join-ec2-*`, `-retry-join-azure-*` and
|
||||
`-retry-join-gce-*` parameters and their usage will be translated to a
|
||||
corresponding `go-discover` config string.
|
||||
|
||||
The supported providers for retry join at this point are Amazon EC2,
|
||||
Microsoft Azure, Google Cloud and Softlayer.
|
||||
|
||||
* For Amazon EC2 use:
|
||||
|
||||
`provider=aws tag_key=xxx tag_value=xxx [region=xxx] [access_key_id=xxx] [secret_access_key=xxx]`
|
||||
|
||||
This returns the first private IP address of all servers in the given region
|
||||
which have the given `tag_key` and `tag_value`. If the region is omitted it
|
||||
will be discovered through the local instance's [EC2 metadata
|
||||
endpoint](http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instance-identity-documents.html).
|
||||
|
||||
Authentication is handled in the following order:
|
||||
|
||||
- Static credentials `acesss_key_id=xxx secret_access_key=xxx`
|
||||
- Environment variables (`AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`)
|
||||
- Shared credentials file (`~/.aws/credentials` or the path specified by `AWS_SHARED_CREDENTIALS_FILE`)
|
||||
- ECS task role metadata (container-specific).
|
||||
- EC2 instance role metadata.
|
||||
|
||||
The only required IAM permission is `ec2:DescribeInstances`, and it is
|
||||
recommended that you make a dedicated key used only for auto-joining.
|
||||
|
||||
* For Microsoft Azure use:
|
||||
|
||||
`provider=azure tag_name=xxx tag_value=xxx tenant_id=xxx client_id=xxx subscription_id=xxx secret_access_key=xxx`
|
||||
|
||||
This returns the first private IP address of all servers for the given
|
||||
tenant/client/sucbscription with the given `tag_name` and `tag_value`.
|
||||
|
||||
* For Google Cloud (GCE) use:
|
||||
|
||||
`provider=gce project_name=xxx tag_value=xxx [zone_pattern=xxx] [credentials_file=xxx]`
|
||||
|
||||
This returns the first private IP address of all servers in the given project
|
||||
which have the given `tag_value`. The list of zones can be restricted through
|
||||
an RE2 compatible regular expression. If omitted, servers in all zones are
|
||||
returned.
|
||||
|
||||
The discovery requires a
|
||||
[GCE Service Account](https://cloud.google.com/compute/docs/access/service-accounts)
|
||||
for which the credentials are searched in the following locations:
|
||||
|
||||
- Use credentials from `credentials_file`, if provided.
|
||||
- Use JSON file from `GOOGLE_APPLICATION_CREDENTIALS` environment variable.
|
||||
- Use JSON file in a location known to the gcloud command-line tool.
|
||||
On Windows, this is `%APPDATA%/gcloud/application_default_credentials.json`.
|
||||
On other systems, `$HOME/.config/gcloud/application_default_credentials.json`.
|
||||
- On Google Compute Engine, use credentials from the metadata
|
||||
server. In this final case any provided scopes are ignored.
